Custom Lightweight Media
- A massive 8 acre planted roof area covers this 60 million gallon drinking water reservoir
- Total of 15,600 cubic yards of custom engineered lightweight growing media was required to ‘cap’ the concrete reservoir roof deck
- The Custom Engineered lightweight media performs similar to a USGA golf green rootzone, but at only 50-55% of the loose bulk density.
